Antimicrobial resistance pattern in Campylobacter strains isolated from both no-antibiotics-ever (NAE) and conventional broiler complexes: Genotypic and phenotypic characterization.

ABSTRACT: Drug-resistant Campylobacter is a serious public health concern because of its increasing resistance to clinically important antimicrobials. To determine the antimicrobial resistance (AMR) pattern, the phenotypic and genotypic characteristics of Campylobacter isolated from two commercial integrated broiler complexes (No-Antibiotics-Ever (NAE) and Conventional) were studied. Genotypic analysis of AMR genes were identified using ResFinder while the phenotypic resistance test was performed using the broth microdilution method. Odds ratio and 95 % confidence limits were calculated for complex types and stages of broiler production (α=0.05). The AMR genes identified were bla_OXA-61 (29 %), bla_OXA-184 (4 %), tet (O) (13 %), tet (O/32/O) (12 %) and aph (3')-III (7 %). The phe
